The most notable wind report came from Walcott, IA, where a wind surge in the line of thunderstorms produced an estimated gust of 65 MPH. Hail to the size of quarters was observed in Muscatine, IA and Bettendorf, IA.

Additionally, torrential rainfall from thunderstorms lead to rainfall amounts over one inch in the Quad Cities, which produced brief flash flooding along River Drive in Moline, IL.
